ANIMAL-sLlNelNe RAILWAY.-

SPECIFIGATION'formingpart of Letters Patent No. 261,316, dated July 18, 1882. Application filed February 1, 1882. (No model.)

To all whom tt may concern Beit known that I, RICHARD J oHN DAvIEs, a citizen ofthe United States,residing at Cambridge,.in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Animal-Slinging Railways; and Ido hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others sklledin the art to which itappertains to make and use the same, refe-rence being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to suspension ot' railtransits employed in slaughtering-establishments to convey the dressed carcasses into and out ot' refrigerating chambers or apartments, in which a flat rail standing on edge is suspended horizontally from hangers secured to the ceiling of the apartment or structure, the

carcasses being slung from a hook swiveled to an arm which is supported upon a grooved roller that travels upon the rail.

In myinvention I convert the lower part ot' the hanger into aclasp, in which the rail isdeposited and by which it is mainly supported 5 and,to prevent slipping ofthe rail in the han ger,

- I employ with each hanger a set-screw, which screws through one side of the same and against the rail, a longitudinal groove being preferably formed in such rail to receive the end of the screw.

The drawings accompanying this specification represent, in Figure l, a vertical section of the rail andfhanger of an animal-slinging railway as heretoforel constructed. Fig. 2 is an isometric elevation, and Fig. 3 a section, ot'

my'improved construction.-

In said drawings, A represents the rail 5 B B, the hangers; E E, the hooks on which the slaughtered and dressed animals are slung; F F, the pendent armson which the said hooks are suspended 5 and GG, the grooved pulleys,

pivoted to the upper part of said arms and traveling upon the rail A.

In carryingoutmyimprovements I continue the lower end of each hanger into a lip, a, which I extend beneath the rail and turn up outside of the latter, thereby providing a clasp or seat, which not only firmly upholds the rail, but ettectually prevents turning or twisting ot such rail in its supports and relieves the bolts of the labor of its support. Moreover, I :torm in the lower part of one side of the rail A a shallow longitudinal groove or indentation, b, of any desired form in cross-section,and opposite this groove I screw through the adjacent side of each hanger a set-screw, c, the point of this screw entering the groove or indentation b, thereby preventin g end-play or lifting of the rail.

When it is desired to remove or to change the position ot' a rail it is only necessary to loosen the set-screws which bind it to permit this to be done. The construction is simple, durable, and strong.

I claim- 1. In combination with the hanger terminating at bottom in a clasp or chair having opposite side walls to inclose and support the rail in an upright position, a set-screw screwing through one of Vsaid walls and adapted to clamp the rail against the opposite wall.

2. In combination, the hanger terminating at bottom in a clasp or chair to uphold and steady the rail, the'rail with its groove or in dentation and the set-screw screwing through one side or wall of the clasp and adapted to enter the groove of the rail and to clamp such rail between it land the opposite side or wall of the clasp.

In testimony whereoflaffix my signature in presence of two witnesses.

RICHARD JOHN DAVIES.
